Damaged Glass
A seal that is airtight is essential for double pane windows to work correctly. The most typical indication that a seal is failing is condensation forming between the glass plates. Condensation between glass plates are not a major issue and can be resolved however it is a sign that your glazing unit needs replacing. If you have an older double glazed window, this could require replacing both the glass and the frame. If the frame is in good shape you might be able to save money by simply replacing the glass.
Glass is fragile, and it's not uncommon for double-pane windows to develop cracks over time. If the cracks weren't caused by mechanical damage or an unusual impact on the window it is possible to repair them with epoxy and some elbow grease. Follow the instructions of the manufacturer and scrub the crack with a moist cotton cloth. Then apply the epoxy to the crack. Let the epoxy completely dry before applying paint and sanding to the repaired area.
It's also possible to keep cracks from spreading by using an easy strip of masking tape. One strip of tape on both sides of the crack area is enough to stop superficial cracks, such as stress cracks caused by low temperatures, from escalating. If you notice deeper cracks in your glass that are already present, it's best to contact a professional for the repair.

Condensation Build-Up
The good news is that condensation between window panes is normal. It's caused by a disparity between air temperature and humidity levels and causes water vapour in the air to condense upon contact with cold impenetrable surfaces such as windows. This is usually a good thing in winter, as it stops loss of heat.

Additionally, there are specialist companies who will fix condensation build-up in double-glazed windows by drilling holes into the window unit and then injecting or pumping a special desiccant to eliminate the excess moisture. This is a more complex process that requires the sealed unit to be removed from the frame, opening up each glass pane, cleaning them thoroughly and then refilling with desiccant before sealing them up. This is usually more expensive, however it's worth checking that any firm you choose to use is insured and is registered with FENSA.
